Research Areas
I am interested in the theoretical study of important unsolved problems in condensed matter physics, such as room-temperature magnetic semiconductors, room-temperature quantum anomalous Hall effect, and room-temperature superconductors. Numerical calculations combined with model calculations are used to study the novel macroscopic quantum physical phenomena exhibited by microscopic interactions such as spin exchanges, multi-orbit interactions, spin-orbit coupling, and electron correlations, and under various control methods such as doping, strain, two-dimensional, and heterostructures.
